Title: Injection of simulating-noise signals
IPC: G06F11/26
Filed: 1981-03-06
Abstract: A simulated-noise signal 3 is injected on the power line of the equipment under test without loss of AC power to the equipment, by a series resonance 4, 5 circuit having a resonance frequency equal to that of the AC power supply. The circuit is connected in the power line L1, L2 in series with the equipment 2, and a capacitor 6 is connected to the power line in parallel with the series resonance circuit and the equipment. Therefore, the simulated-noise signal 3 is injected on the power line through the capacitor at both ends of the resonance circuit, and AC power loss is prevented by use of the resonance circuit. A switching element 7 is used to short-circuit the resonance circuit for a period when the noise simulation is not carried out. Simulation of lightning strikes and ringing-surge due to turn-on or -off of other equipment is described.

Title: Method of combatting plant diseases
IPC: A01N63/00
Filed: 1981-12-17
Abstract: Yellows diseases have devastated crops, particularly of citrus fruits. They are associated with (and ostensibly caused by) very small mycoplasma or spiroplasma type organisms (MLO for short). Attempts at chemical control of MLOs have been unsuccessful. The present invention is based on a remarkable new finding that biological control can be achieved by introducing into the phloem of the plant a virus which is infective to the MLO. The invention is of particular interest in relation to diseases associated with Spiroplasma citri, especially in citrus plantation. Plant tissue comprising phloem containing the virus particles is included in the invention as useful for transmitting disease resistance to plants by grafting.

Title: Regulating water circulation from sedimentation basin to overflow tank
IPC: B01D21/00
Filed: 1982-02-24
Abstract: A water recycling plant has a sedimentation basin (1) connected via water outlet holes (4) to an adjacent overflow tank (6). Water for use in a process plant (11) is drawn from the overflow tank and circulated back to the basin (1). The rim of the basin (1) and the rim of the overflow tank (6) are arranged at substantially the same level which is sufficiently far above the outlet holes (4) to provide a head of water at which the overflow water from the basin to the overflow tank corresponds to the maximum water consumption of the process plant (11). The water levels in the basin (1) and overflow tank (6) are regulated to be above the outlet holes (9). The launder (5) may act as the overflow tank. Slurry removal from the bottom of the sedimentation basin (1) is controlled at (9) by the water level in the basin actuating a maximum/minimum alarm. The arrangement ensures that an adequate flow of overflow water is available at all times to meet the demands of the process plant (11) fed from the overflow tank (6) and the addition of fresh water or disposal of excess process water is minimised. <IMAGE>

Patent GB-2107798-A (GB)
Title: Liquid pumping apparatus
Inventor: CRAGGS THOMAS ARTHUR
IPC: F03C1/007
Filed: 1982-04-26
Abstract: A pumping apparatus for pumping liquids such as slurrys comprises a pumping cylinder/piston driven by the piston/cylinder (16, 18) of an operating device, the supply of fluid under pressure either to an upper port (16a) of the cylinder (16), or the lower port (16b) of the cylinder, being controlled by valve mechanism (28). The fluid pressure circuit powering the operating device includes a regenerative branch 60, through which fluid under pressure flows from the low pressure side of the operating device directly back to the high pressure line of the fluid circuit, upstream of the motor supplying fluid under pressure. In this manner, the apparatus can operate both at a high speed, low resistance mode, and at a later stage in a pumping operation, at a lower speed, higher resistance mode. In this manner, not only is a saving of energy obtained, but (because of a reduction of work done on the fluid) water cooling of the fluid circuit may be dispensed with. <IMAGE>

Patent GB-2318006-A (GB)
Title: A radar apparatus
Inventor: CASHEN ERNEST ROSCOE
IPC: G01S7/292
Filed: 1982-08-11
Abstract: A radar apparatus (Figure 5) includes an oscillator (102) arranged to generate pulses of microwave radiation which are transmitted at T x . Some of the radiation generated by oscillator (102) is tapped off before transmission and applied as a local oscillator (LO) signal to a mixer (104). The mixer also receives a corresponding return pulse and produces a video pulse having a pulse length related to the delay between transmission and reception, i.e. the range of a target. The video pulse is compared in different channels (1', 2') of the apparatus with respective reference signals R1,R2 each of a form such that the integral thereof with time vanishes over the interval of occurrence of each generated pulse. This alleviates adverse effects of interference signals which may be derived from an external source and or by direct transmission between the transmitter T x and the receiver R x . The transmitted and generated pulses have the same pulse length, and one of the reference signals has an amplitude in the negative polarity sense significantly greater than in the positive polarity sense. In another example (Figure 1) each transmitted pulse has a pulse length of only half that of the corresponding generated pulse and both reference signals are bipolar square waves.
